To atl whom t may concern: f e it knownthat l, Renner Sonoran, a

citizen of the United States, residing at San rancisco, in the county of San 'F ancisco e and State of California, have invented new and useful improvements in Rotary-Pump Iechanism, of which the following is a specification. This invention r to tary pump in eheni provide mechanism which the centrally l other .pumps of this class thus permitting of the Water being discharged in an unobstructed column; which mechanism will be rapid and self-contained and With 'bearing surfaces ot ample size; which will be of great ei'iciency, and in which the number of leakage gaps will be 2o reduced and obstructions eliminated, thus obtaining the delivery of a maximum amount of Water from a given size of pump runner.

The central shaft ein designs of rotary Well of great Weakness, as lit in order to reduce the thereby to a minimum, a multiplicity of small bea 3o somewhat diflicult to aline.

these bcarings'haveto be protected from sand and grit, which are often carried in the Water. The proper lubrication of such bearings with certainty is also difiioult of accomplishment.

In the accompanying drawing, Figure l is a longitudinal vertical section of my improved pump havingw a rotary suction pipe attached; Fig. 2 is a similar view of a pump 4o with a stationary suction pipe. attached.

Jteiierri-nggj to the drawing, the runners l of the pump are attached, as shown at 2, to a cylindrical housing 3, which in turn is fastened by means of a top casting l to anv outer pipe 5, which carries et its upper end, above the ground, a pulley 3 for driving said pipe 5, housing 3, the attached pump runners l. At suitable intervals bearings 7 for the pipe 5 are supported upon inside or discharge pipe 8, which is stationaryv`v and secured Vat the top to a trame 9, secured upon the ground, pump diiliusers 10 being;` supported by said tube 8. Only two bearings 1" are here shown, and they are shown as ball bearings. 'It is obvious, however, that any elates to an improved roem, and the object is to of this character from coated shaft used in all Will be eliminated,

ployedby all other pump is en element has to be very thin obstruction caused d as it requires a Specification of Letters Patent.

Vsure to the tirs number of such bearin Y cording to thel depth of the-Well, and sign of the bearings\themselves cv1 ed in many Ways. The uppermost l0 has a hub 1l `for a stub shaft i2, employed for supporting the lower di (one only being` here shown/l, The a space 13 between the pipes and as nearly water-tight as possible bvo stu ing box le, or by any othersuitable The bottom end of the pipe 5 i; bo the lowermost runner i, which ai a suction pipe l5, which may here a or-heliX 16 et its bottom, or inside i' tire length, Ato propel the Water under t pump runner. 13, which may be under pressure, erwinv leakage between-the runners and ditli. may communicate by holes 17 4and e eh ber l5 With thesuction space to relieve pressure on the runners.

Fig. 2 illustrates the modified to permit or" a stationary' suct pipe, by extending the stub carry an inlet casting 18, which has Wa, seal channel 19 het 4'u to prevent air leakage, which would rc the suction lift. Bolted or screwed casting 18 is the suction pipe 21'), wliio" therefore stationar and is' in aline with the dilusers l0 and tl e nXed disci pipe 8. In both'forms of the invention 'o 6 is shown for rotating the outer tub instead thereof, gearing can' be arrang direct connection to n electric mol other source of power. Also the outer can be shortened and geared below tbc face of the ground, the gearing being ated by means of a shaft extcndin to the discharge pipe 8 and With ov supported by said pipe. At the npr of said vertical driving shaft either ley or gearing can be used for rota have herein illustrated the mechanisr as disposed vertically, as is required for Wells, but the invention is also adapted 'for a horizontal or inclined discharge. Wi so used With a stationary suction p forms a very compact and etlicient delivering a large volume or' Water, es quired for drainage and irrigation.
